Stokes's law is the basis of the falling-sphere viscometer, in which the fluid is stationary in a vertical glass tube. A sphere of known size and density is allowed to descend through the liquid. If correctly selected, it reaches terminal velocity, which can be measured by the time it takes to pass two marks on the tube.

The aim of my investigation was to explore the viscosity of golden syrup using stokes law to calculate the viscosity of the liquid.

Apart from superfluids, liquids and gasses have the property of viscosity. Viscosity is measured in Pascal-seconds; this describes its resistance to deformation and the ease that which it flows. Viscosity is internal friction this is due to intermolecular forces, this is affected by temperature and pressure if gas but just temperature if liquid. Newtonian fluids viscosity stays the same regardless of temperature or any other force.

Liquids with a high viscosity flow slowly (like golden syrup), whereas liquids which have lower viscosities flow faster (like water). There are many ways to measure viscosity. However I chose to do so by using a chrome ball bearing as this was the only sphere shaped object available to be
